Hey there
@Dom, since you did not question the Build Date at time of purchase, the dealer intentionally passed on a Dec 2017 build Stinger to you, and " Yes " it would have been siting around for over a year, the other most important thing is you have a MY18, not a MY19 with the upgrades, if you were given a MY19, you would have upgrades like a bezel less screen, ambient lighting and the metal plates in the rear hatch, and Michelin tyres all upgrades here in Australia on the MY19, personally i would not accept it, and insist you expected the most current MY19, 2019 Build Stinger, i wouldn't stand for it, myself.
